Broadleaf arrowhead (Sagittaria latifolia), also known as common arrowhead, is a perennial aquatic plant that forms colonies along rivers, lakes, and wetlands. It stands elegantly above the water with its large, arrow-shaped leaves. In summer, it produces clusters of white flowers with three petals and three green sepals, atop stems that can reach up to 1.2 metres in height. Adapted to aquatic environments, this plant is ideal for pond or stream banks in water gardens.
Medicinal and Culinary Uses
Broadleaf arrowhead is an edible plant with several consumable parts. Young leaves, shoots, and tender inflorescences can be eaten raw in salads or cooked. However, its tubers, rich in starch, are the most prized part. Once cooked, these tubers have a texture similar to potatoes and can be incorporated into various dishes.
Ecological Roles
Broadleaf arrowhead plays an essential ecological role by supporting wetland biodiversity. Its tubers provide a food source for many aquatic animals, such as ducks, turtles, and various mammals. Additionally, this plant aids in water filtration and oxygenation, helping to remove excess nutrients and impurities. Cultivating the broadleaf arrowhead in aquatic settings supports ecosystem health and stabilizes banks with its robust root system.
Broadleaf arrowhead seeds require cold stratification to ensure germination. See the cultivation notes below for more details.
